991.1 GT3 vs 991.2 GT3: over $100,000 apart, and the 991.1 engine question has answers
In any 991.1 GT3 vs 991.2 GT3 comparison, the first thing shoppers notice is that the earlier car costs far less. The next question is usually about 991.1 GT3 engine problems, and whether they're the reason.
Partly, yes. But the 991.1's engine problems are documented, and Porsche dealt with them. If you know what paperwork to ask for, the 991.1 is the value GT3. Here's how the two compare.
Figures are US sales in US dollars from our Porsche GT3 (997 and 991) Buyer's Report, priced as of October 16, 2026. Sources are named at the end.
How much is a 991.1 GT3 vs a 991.2 GT3?
From our GT3 (997 and 991) report, US sales in US dollars, priced as of October 16, 2026:
| Version | Opening offer | Target | Walk-away | Sales (24 mo) |
|---|---|---|---|---|
| 991.1 GT3 (PDK) | $122,700 | $145,000 | $158,000 | 10 |
| 991.2 GT3, manual (not Touring) | $212,400 | $250,000 | $287,500 | 13 |
The 991.1 target is $105,000 below the 991.2 manual, at 58% of its price.
991.1 GT3: prices rose through 2026. The first three sales of the year went for $107,000 to $127,000 and the last five for $128,000 to $184,800. Eight sold in 2026 at a $133,000 median. The report says to expect to pay near the $145,000 target, not the year's median.
991.2 GT3 manual: nine sold in 2026 for $201,000 to $306,000, centered on the $250,000 target. The latest, a 1,300-mile car, brought $306,000.
991.2 GT3 Touring: only six US sales in 24 months, so the report doesn't set a target. The five sold in 2026 brought $273,500 to $382,000, a $295,000 median. Don't pay Touring money for a non-Touring car.
The 991.2 PDK isn't priced. There are no confirmed US PDK sales in our data, so don't use the manual target for one.
Which gearboxes do the 991.1 and 991.2 GT3 have?
The 991.1 GT3 (MY2014–2016) is PDK only. The 991.2 GT3 (MY2018–2019 in the US) offers PDK or a six-speed manual, and the Touring is manual only. So the comparison above is a PDK 991.1 against a manual 991.2. If you want three pedals, the 991.1 isn't your car regardless of price.
What were the 991.1 GT3 engine problems?
Two separate issues gave the 991.1 its reputation.
The 2014 engine replacements
A loosened connecting-rod screw damaged the crankcase and leaked oil that ignited in two cars. Porsche replaced the engines in all 785 MY2014 GT3s. In the US, that was recall 14V090000, which covered 209 cars built October 19, 2013 to January 16, 2014.
Finger followers
A metallurgical defect in some batches of valvetrain finger followers caused high-rpm misfires. Porsche announced a transferable 10-year, 120,000-mile engine warranty for failures from this cause, reported by Road & Track.
That warranty runs 10 years from the car's in-service date. For MY2014–2016 cars, those dates fall around 2024 to 2026, so on many cars it has ended or is about to. Ask a Porsche dealer for the in-service date and whether the cover still applies to the VIN. Don't assume it does.
What paperwork should a 991.1 GT3 have?
For a MY2014 car, ask for dealer records of the replacement engine under recall 14V090000. For any 991.1, ask for records of finger-follower or camshaft work. A 2014–2016 car with no records is the one to avoid.
Then get the over-rev log. Porsche's Technical Information 0335 (12/13, revised March 21, 2024) covers the 991 GT3 from model year 2014. The engine computer (DME) stores ignition counts in each over-rev range and the engine hours at the last event. On a six-range log, ranges 1 and 2 mean engine damage possible, 3 and 4 probable, and 5 and 6 mean damage has generally occurred. Porsche says damage linked to over-revs can't be repaired under warranty or goodwill.
Get a dated Porsche dealer printout before you talk price. A clean answer is no events in range 3 or higher. Refusal to provide one is a red flag. The same printout matters on the GT3 RS; see our 991.2 GT3 RS Weissach pricing guide.
Can a 991 GT3 get a Porsche warranty?
Porsche Approved Certified Pre-Owned in the US accepts the current model year plus the 13 previous model years, under 124,000 miles. In 2026 that includes both 991.1 and 991.2 GT3s that pass the dealer inspection. The 997 GT3s don't qualify.
A car with a bad over-rev log or missing records may not pass, so it has no factory warranty route. Price it that way.
What else to check on a 991 GT3
From the report's inspection list:
- Dealer recall printout for the VIN. That covers 14V090000 on 2014 cars and 19V875000, an owner's-manual supplement for child-seat instructions on MY2014–2016 and MY2018–2019 GT3s.
- Track use: Repasi Motorwerks notes rear-main-seal leaks are common on GT3s after track use (an engine-out fix), along with wheel-bearing wear and carbon-ceramic rotor cracking. Ask about any cage or harness installs.
- Service schedule: the 991.1 needs oil every 6,000 miles or 1 year from build week 45/2014 (12,000 miles before that), spark plugs every 12,000 miles or 2 years, and PDK clutch fluid every 48,000 miles or 6 years. The 991.2 gets an inspection every 12,000 miles or 2 years.
- History: none of the 100 comparable US sales since 2020 in our records disclosed an accident or stated a clean history. Run NMVTIS, NICB VINCheck and a history report on every car.
A pre-purchase inspection for 911 GT cars is $649 at Vehicle Inspectors.
What about the 997 GT3?
The 997.1 and 997.2 GT3s had only five US sales each in 24 months, so the report lists them without targets. Mileage sets the 997.2 price: $355,500 at 11,000 miles and $270,000 at 17,000 miles in 2026, against $150,497 at 69,600 miles in 2025. These are Mezger-engined cars with bonded coolant pipes. BBi Autosport lists its welding service at $1,650, with engine removal extra. The 996 Turbo shares this issue; our 996 Turbo price guide covers the fix.
Frequently asked questions
Were the 991.1 GT3 engine problems fixed?
Porsche replaced the engines in all 785 MY2014 GT3s (US recall 14V090000) and announced a 10-year, 120,000-mile engine warranty for finger-follower failures. Ask for the records and a clean over-rev printout.
Does the 991.1 GT3 finger-follower warranty still apply?
It runs 10 years from the in-service date, so on many MY2014–2016 cars it has ended or is about to. Ask a Porsche dealer to check the VIN.
Was the 991.1 GT3 offered with a manual?
No. The 991.1 GT3 is PDK only. The 991.2 offers PDK or a six-speed manual, and the Touring is manual only.
The bottom line
A 991.1 GT3 with documented engine history and a clean over-rev printout is the value GT3, at a $145,000 target against $250,000 for a 991.2 manual. Check whether the finger-follower warranty still applies rather than counting on it. And if the paperwork is missing on a 2014–2016 car, keep looking.
